451969 divided by 12 
We want to figure out the number of times 451969 can be divided by 12.

Let's proceed to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

On to step 2:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 36 from 45 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Moving on to step 3:
When dividing 91 by 12, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 84 away from 91, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 12

Going ahead to step 4:
If we divide 79 by 12, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 376.0
If we subtract 72 from 79, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 12

On to step 5:
12 goes into 76 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 3766.0
Deduct 72 from 76 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 12

Going ahead to step 6:
If we divide 49 by 12, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 37664.0
Subtract 48 from 49 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
12 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 37664.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 37664.08
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 37664.083
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 37664.0833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 37664.0833 with a remaining 4e-05.
